The project is part of the 2006 voter-approved RTA 20-year multimodal plan. The project scope consists of roadway and bridge improvements necessary to connect Sunset Road from I-10 to River Road. The County intends to jointly construct with the adjacent Arizona Department of Transportation widening project from Ina Road to Ruthrauff Road, in order to reduce construction costs and impacts to the traveling public.

    • Final Design started March 2021, and will be completed in March 2022.
    • Construction timeline is estimated to start October 2022. The construction timeframe is anticipated to be between 18-24 months.
